ELECTRIC-BOX CONNECTION.

Specification of Letters Patent.

Patented Aug. 5,1913.

Application filed June 6, 1911. Serial No. 631,582,

To all whom it may concern:

Be it known that I, FREDERICK H. WARD, a citizen of the United States, residing in the borough of Brooklyn. in the county of Kings and State of New York, have invented certain new and useful Improvements 1n Electric-Box Connections, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in outlet boxes more particularly adapted for use in electrical wiring and has for its principal object means for binding conduits within the same.

To this end the invention contemplates a binder adapted to force the conduitslaten ally out of their normal path thereby'binding the same against the interior walls of the entrant port-ions of the box.

In the accompanying drawings I have illustrated in Figure 1 a plan view of a form of outlet box illustrating an application of my invention. Fig. 2 is a cross section of the same on the line 2-2 of Fig. 1, and Fig. 8 is another cross section on the line 3-3 of Fig. 1. Fig. i is a plan view of the binder, and Fig. 5 is a broken plan section of a modification.

Referringnow more particularly to Figs. 1 to 3 inclusive it willbe observed that the entrant portions 7 of the box are slightly at an angle to the walls of the box thus producing a tapering effect and are cut away at their adjacent sides to allow for the introduction of the binder shown in Fig. 4. This binder is preferably provided with a central hole 8 which is tapped to receive a screw such as 9 and the tops of theentrant portions may be connected by a suitable web or bridge such as 10 suitably bored to allow the screw 9 to pass therethrough. This web or bridge is also provided with a nose or projection such as 11 and a guide such as 12 may also be provided at the wall of the box. This determines the course of travel of the binder 13 illustrated in Fig. 4. From this it will be seen that by operating the screw the binder is drawn upwardly following the guides 11 and 12 until the sides 14-45 engage the sides of the ends of the conduit thus securely binding them within their entrant portions. From this it will be understood that if only one conduit is in place the binder will bind the same and hold it securely equally as well as it both conduits are in position.

In Fig. 5 the binder is shown at 22 and in this case bears down upon the cables 23-24 instead of upwardly as shown in Figs. 1 to 3 inclusive' In this case the binder is not tapped to receive the threads of the screw but the bottom of the boxis tapped and when the screw enters the threads in the hole at the bottom of the box,the binder 22 is drawn down upon the cables 23-34: by the head of the screw. Suitable guides may of course be employed if desirable.

Of course it will be understood that various modifications maybe made without departing from the spirit of the invention as set forth in the claims.

I claim:

1. In an outlet box, an entrant portion adapted to receive the ends of conduits, and binding means adjacent thereto ada ted to secure said conduits or either of t em in position, said binding means comprising a traveling binder and a screw, said binder adapted to ride upon the threads of said screw, guides adjacent to said entrant portion adapted to be engaged by said binder and said screw adapted to drive said binder along said guides, and upon said conduit.

2. In an outlet box, an entrant portion adapted'to receive the ends of conduits, and binding means adjacentthereto adapted to secure said conduits or either of them in position. said binding means 7 comprising a traveling binder and ascrew, said binder adapted to ride upon the threads of said screw, guides adjacent to said entrant portion adapted to be engaged by said binder,

and'said screw adapted'to drive said-binder along said guides and uponsaid conduit, whereby the ends of said conduit are forced apart.

3. In an outlet box. an entrant portion comprising two inlets for the ends of conduits. said inlets approaching each other at their inner ends, and binding means adjacent thereto adapted to secure saidconduits or either f them in position, said binding by said binder, and said screw adapted to Witnesses:

means comprising a traveling binder and a In testimony whereof I afiix my signature screw, sa d binder adapted to ride upon the in presence of two wltnesses.

threads of said screw, guides adjacent to said entrant portion adapted to be engaged FRLDERIOK WARD drive said binder along said guides and Lou sa ENDERLE, upon said condult. 4 THOMAS A. HILL.
